  • Monolithic catalyst used for carbon dioxide hydrogenation reaction and method for preparing same
    Patent number: 11338273
    Abstract: A monolithic catalyst used for a carbon dioxide hydrogenation reaction and a method for preparing the same. The catalyst comprises a carrier, a coating, and active components. The carrier is a honeycomb ceramic. The coating and the active components are separately applied to honeycomb ceramic hole walls from inside to outside. Moreover, each of the honeycomb ceramic holes is divided into an upper segment and a lower segment, and different active components are separately loaded on the two segments. The method for preparing the monolithic catalyst comprises first applying a coating to a honeycomb ceramic by means of impregnation to obtain a coating-containing carrier, and then applying active components to an upper segment and a lower segment of the coating-containing carrier successively by means of impregnation to obtain the monolithic catalyst.

  • Method for preparing copper-zinc-based catalyst used in synthesis of methanol through COhydrogenation
    Patent number: 10010875
    Abstract: Disclosed is a method for preparing a copper-zinc-based catalyst used in synthesis of methanol through CO2 hydrogenation, and ultrasonic waves are used for control over crystalline phase's composition of a catalyst precursor. Further related to is a catalyst prepared by such a method. An amount of aurichalcite in an active catalyst precursor can be improved through the method, and the specific surface area of the metal copper in a reduced state catalyst is high. The catalyst presents high activity and hydrothermal stability, and promotes high space time yield of methanol in the synthesis of methanol through CO2 hydrogenation.
